The electron in a hydrogen atom at rest makes a transition from `n = 2` energy state to the `n = 1` ground state.
find the energy `(eV)` of the emitted photon.

The electron in a hydrogen atom at rest makes a transition from n = 2 energy state to the n = 1 ground state. Assuming that all of the energy corresponding to transition from n = 2 to n = 1 is carried off by the photon. By setting the momentum of the system (atom + photon) equal to zero after the emission and assuming that the recoil energy of the atom is smaller compared with the n = 2 to n = 1 energy level separation , find the energy of the recoiling hydrogen atom.
